A prospective study of breastfeeding intentions of healthy weight and overweight women as predictors of breastfeeding outcomes

Objective Women with a higher BMI are at increased risk of breastfeeding for a shorter duration, however it is unclear if weight status itself or other factors such as feeding intentions are responsible for early breastfeeding cessation. The aim of this study was determine the influence of maternal pre-pregnancy weight status on infant feeding intentions during pregnancy using a validated scale and assess whether high intentions to exclusively breastfeed measured during pregnancy predicted feeding mode at discharge and at 4 months postpartum in both healthy weight (Hwt) (BMI 25 kg/m2) women. Design This prospective, observational study commenced when participants were <20 weeks gestation, continuing until four months post partum. Self-administered questionnaires assessed pre-pregnancy weight, infant feeding intentions at 36 weeks gestation, and breastfeeding practices at hospital discharge and 4 months postpartum. Hospital records provided details of delivery mode, gestation and breastfeeding during hospital stay. Binary logistic regression analyses were used to compare weight groups on the breastfeeding beliefs and practices adjusting for selected covariates Participants and setting A consecutive sample of pregnant women (n=715) were recruited from an Australian metropolitan hospital between August 2010 and January 2011.
